OKR10 Construction Stormwater

Overview

Stormwater runoff from construction sites carries significant amounts of sediment and other pollutants which have the potential to harm streams, lakes, and wetlands. As stormwater flows over a construction site, it can pick up pollutants like sediment, debris, and chemicals, and transport these to a nearby municipal storm sewer system or directly to a stream, lake, or wetland. Sediment in waterbodies from construction sites can reduce the amount of sunlight reaching aquatic plants, clog fish gills, smother aquatic habitat and spawning areas, and high volumes of runoff can cause stream bank erosion and impede navigation. Controlling erosion and sediment can significantly reduce the amount of sedimentation and other pollutants transported by stormwater runoff from construction sites. The Oklahoma Pollution Discharge Elimination System (OPDES) stormwater program, authorized by the NPDES stormwater permitting program, requires construction site owners/operators to obtain coverage under the OPDES Construction General Permit OKR10 to discharge stormwater from their construction sites and implement appropriate pollution prevention controls/techniques to minimize pollutants and reduce stormwater runoff.

A permit is required before construction activity can start at a site. Discharge of stormwater from a construction site without first obtaining a permit from DEQ is in violation of Title 27A O.S. §2-6-205 of the Oklahoma Statutes. As part of the application, the owner and/or operator must develop and implement a Stormwater Pollution Prevention Plan (SWP3) to minimize pollutants and reduce stormwater runoff. The applicant may need additional permit coverage from the city/county government for the construction site. The applicant must check with them before submitting a Notice of Intent (NOI) to DEQ.

Who Needs a Permit and How to Apply

Who needs a Permit?

You will need an OKR10 permit if you are the owner or operator for any construction activity disturbing:

  • One acre or more, or
  • Less than one acre if that activity is part of a “larger common plan of development or sale” that is greater than one acre.

For more assistance in determining whether an OKR10 permit is required for your project, please refer to: OKR10 Decision Flow Chart

How to Apply for a Permit?

Before filling out an NOI, understand the requirements of the current OKR10 General Permit for Construction Activity, identify the latitude and longitude of the entrance gate of the facility, identify the receiving water body, check whether the facility is located along a Sensitive Water or in a Sensitive Watershed or a Scenic River Watershed, and prepare a new or update an existing Stormwater Pollution Prevention Plan (SWP3) in accordance with the requirements of the OKR10 Permit.

  • Completed NOI (Construction Stormwater Notice of Intent (PDF))
  • Site map(s) of your facility, and
  • Payment for all applicable fees (Application fee of $100 plus, for new construction site/projects, annual fee of $347.71. Note: Existing permittees will be invoiced for the annual fee.)

You can submit your NOI and pay the fees using a credit card (only Visa or Master Card are accepted) through DEQ’s online NOI system by clicking on the button at the top of this page.

Alternatively, if submitting your NOI by mail, you can pay by attaching a check for the applicable fees payable to DEQ with your NOI or by calling DEQ Finance at (405) 702-1130.
